Shenzhen Grephon’s（Stevin ,8-6-1-3-4-8-0-7-3-3-8-0-5) LED panel light major components .1.LED Panel light aluminum frame:Is the main channel of LED heat radiation, simple appearance, using mold mold stamping, low cost, processing cost is low; die casting aluminum frame IP levels can be a little higher, surface texture, the overall appearance, but the higher cost of upfront investment mold.2.LED light source:Usually LED lamp uses 2835, others use 3014 and 5050. 3014 and 5050 of low cost, light efficiency is slightly worse, the key is the difficulty in the design of his light guide network. Shenzhen Grephon LED use 2835 high light efficiency mesh point is good.3.LED light guide plate:The side LED light through the network to make the light refraction is derived from the front light guide plate is uniform, LED panel light key points of quality control. Network design is not good, the overall efficiency of light to see the very poor, the general will appear on both sides of the middle light dark, or there is the light into the light where the band, or visible part of the dark area or different angles inconsistent brightness. In order to improve the light efficiency of the light guide plate depends mainly on the network design, the second is the quality of the plate, but not necessary superstition first-line brand of sheet, plate light qualified rate between the often similar. General small LED lights factory are directly buy light guide public use, do not need to re layout design, Shenzhen Grephon LED use the male version usually quality.4.LED diffusion plate:The light guide plate of uniform light derived, can also play a role in fuzzy network. Sheet material or PC material diffusion plate generally use acrylic 2, almost is PS material, acrylic has low cost and light transmittance is higher than that of the PC, acrylic anti aging performance is weak, PC prices slightly expensive, but the anti-aging performance.
